To all whom it may concern: 1

Be it known that I, EDUARD When, a subject of the Emperor of Austria-Hungary, residing at Prague, in Bohemia, Austria-Hunary, have invented certain new and useful mprovements in Processes of Manufacturing Briquets, of which the following is a specification.

According to all processes hitherto known for the manufacture of fodder-cakes, compressed fodder, and the like from lants binding agents must be added in or er to retain the parts of the fodder-plants in the shape imparted to them by the ressing operation. The binding agents empl dyed for this purpose consist in foodstuffsuch as bruised grain, flour, and the like-prepared in the shape of a dough kneaded together with industrial Waste materials of vegetal origin, hay, or chopped hay and then pressed to form fodder-cakes. In order to impart durability'to mixtures of this kind, the foddercakes must then be heat-dried. All those processes have for their sole object to effect a reduction in the volume of such mixtures composed of highly-moistened rich foodstufls and hay or chopped hay; but all of them require. a considerable amount of time and Working expenses, and they sufier under the disadvantage directly due to the use of hay or chopped hay-namely, that losses of the most valuable vegetal and nutritive matter contained in the asses, clovers, combined fodder, and the e are unavoidable. The said losses are causedby the usual methods of harvestingthat is to say, by allowing the plants when mown to lie out upon the standing-place and to dry in the fields by the air and the heat of the sun and under continuous influence of theweather. By the 30'' tion of the dew and in a still higher degree by that of rain vthe mown plants aredeprived of some of their valuable nutritive ingredients, and the agglutinants, such as pentosanes and others, contained in the plants, especially on their surfaces, are chemically altered or Washed away. a

The method forming the object of the present invention renders possible the manufacture of durable preserved fodder bri uets from fodder-plants and without the addition of separate binding agents, the said fodder briquets possessing the full nutritive tenor of the components. a

The improved method enables. the farmer to convert fodder-plants, independentl from atmospheric conditions and at any esired stage of their growth without any losses of the very best ortions of the plants and of the most valua 1e nutritive ingredients, into handy and durable preserve briquets.

The im roved processconsists in that the fresh new y-mown green plant-fodder, either in the mown state or cut into chaff, is admit-, ted into a drying apparatus, where it is deprived of its tenor in water by an artificial dry ng operation, whereafter it is moistened again, but only to such a degree as is necessary to impart to it the suppleness required for the pressing operation and to restore the binding property of the organic agglutinants, such as pentosanes and others contained in the plants themselves for the purpose that at the final pressing of the plants or-portions of plants into briquets they should adhere together and permanently retain the shape imparted to them by the pressin operation.

The .sli ht moistening of t e artificiallydried fodfer-plants or portions of plants may be effected by admitting a current of moist air or by the aid of steam to pass through the same.

Before or after the remoistening of the dry materials consisting of fodderlants they maybe mixed with grains or ot er dry ric foodstufl? without impairing thus the cohesion of the briquets manufactured from the mixture. 1

Having thus fully described the invention, What is c aimed as new is 1. A process of manufacturing preserved briquets from agricultural plants without the loss of nutritive substances, consisting in ar-,

tificially drying the fodder-plants in their en finally briquets from agricultural plants Without the loss of nutritive substances, consisting in artificially drying the fodder-plants in their fresh state at a temperature to prevent the 5 impairing of the a glutinants contained in the fodder-plants, 51611 leading through the artificially-dried fodderplants a suitable fluid so as to moisten them in order to excite the binding" effect of the agglutinants contained in the plants, and then forming the id' moistened plants into briquets.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-
